网考网参考答案：C
网考网解析：
备选答案均为连词，可一一代入后，选择最符合句意的。根据前一分句内容(宣布退休)和后一分句内容(忙于培训他的接班人)，(C)since(自…以来)最恰当。since announcing his retirement在意思上相当于since he announced his retirement，前者使用现在分词来表达，后者使用从句来表达。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
